Soil microorganism biomass is an important soil quality indicator. The microbial biomass of soil was determined by killing and lysing the soil microbes by fumigation with chloroform, irradiation with gamma rays, or irradiation with microwaves. Four soils with increasing carbon concentrations (5, 10, 15, and 30 g kg-1) were analyzed using four methods: the direct application of chloroform, chloroform fumigation, microwave irradiation, and gamma ray irradiation with radiation doses of 15, 25, 35, 45, and 60 KGy. The fungi and bacteria in the soil were quantified by plate counting. Microwave irradiation and gamma irradiation with doses equal to or above 25 KGy killed all the soil microorganisms, but the chloroform methods did not. The carbon liberation... |

The effects of oviposition time, which represents different positions of the follicles in a sequence of posture, were studied on egg weight, chick weight, egg weight loss during incubation, hatchability, embryo mortality and infertility . A total of 19, 820 eggs, layed on the same day, from Cobb® broiler breeders aging 46-week-old were used. The eggs were classified according to the oviposition time posture (corresponding to the time of collection) from 8:30 am, 10:30 am, 12:30 pm, 14:30 pm and 16:30 pm, which represented the folowing treatments: 1st, 2nd, 3rd, 4th and 5th collects, respectively. The experimental design was completely randomized with five treatments and 36 repetitions, and each tray of 96 eggs was considered a repetition. The normal and... |

Thirty-two eggs of Pantanal caiman (Caiman crocodilus yacare) (Daudin, 1802) were incubated at 30° C. After 20 days of incubation at 30° C, the remaining eggs were distributed in the following way: seven at 34° C, seven at 32° C, six at 30° C and six at 28° C. At 32° C and 34° C a 100% hatchability was obtained while at 30° C 83.3% and at 28° C 66.6%. After hatching, the animals were kept for 120 days at the same temperature of their final incubation. Weight (g) control and morphometric (cm) analysis were carried out. The statistic design was totally randomized and the data were treated by regression analysis showing a quadratic behavior ( p<0.05). It was found that weight, total length (TTL), tail length (TL), snout- vent length (SVL), head length... |

Methodological variations in the amount of sample incubated and the type of rumen fluid used are commonly observed. This study evaluated the effect of three sample amounts (0.6, 1.3 or 2.6g DM 100mL-1 of rumen fluid) incubated in rumen fluid buffered (BRF-buffered rumen fluid) or not (PRF-pure rumen fluid) on total gas volume (TV), methane (CH4) production, dry matter degradation (DM Deg) and final pH of corn silage incubated in vitro. The highest DM Deg was reached with the lowest amounts of sample (0.6 and 1.3g of DM 100mL-1 of rumen fluid). The sample amount of 2.6g associated with PRF reduced CH4 production (P<0.05), compared with the amounts of 0.6 and 1.3g DM 100mL-1, which had similar CH4 production (P>0.05). The use of BRF caused no effect on... |

O jacare no Pantanal, e uma especie que ha quase uma decada vem sofrendo enorme pressao de caca clandestina, devido ao valor economico de seu couro e ao impedimento de sua utilizacao na forma de individuos adultos. O uso deste recurso natural necessita de legalizacao para tornar-se um complemento economico para as propriedades da regiao, hoje, exclusivamente sustentadas pela pecuaria. Atualmente, o manejo sustentado da especie, em condicoes naturais, e a forma mais viavel para sua explotacao racional. Baseia-se na coleta de ovos, sua incubacao e a manutencao dos filhotes em cativeiro. Um percentual dos filhotes nascidos, apos alcancarem um porte de mais de 60 cm de comprimento total, quando estao menos susceptiveis as predacoes naturais, serao repostos na... |

Sexual differentiation of the marine leatherback turtle is sensitive to temperature. Incubation of eggs below 29 degree C results in 100% males, whereas incubationa bove 30 degree C results in 100% potential females at hatching. Therefore, the threshold temperature lies between 29 and 30 degree C as has been found for other marine turtles (Caretta caretta, Chelonia mydas ). Among hatchlings from natural nests in French Guiana, 10% were males, 20% were potential females and 70% had an intermediate phenotype. The sand temperature at 60 cm of depth, near one nest, was recorded and was found to vary between 29 and 30 degree C during the presumed thermosensitive period. These results will be useful to marine turtle hatcheries which seek to manipulate sex ratios... |
